I was stationed on Oahu from late 1972 until late 1980, spending 1 year of that time working at Pearl Harbor. Back then, and even today you can still see some of the damage from the December 7 attack besides the two ships still laying on the harbor bottom,
Arizona and
Utah. As Rusty's original post shows there are still damaged buildings on Ford Island, bullet pocked barracks buildings on Wheeler Field and Schofield Barracks. In a small field adjacent to Pearl itself and Waipahu Town is still stored some of the wreckage cut from
Arizona's superstructure but not dumped at sea or salvaged. The field is fenced and only a few special visitors gain access (I was not one.)
There was a 2nd disaster at Pearl Harbor later in the war, the pressure to move men and material on to support the invasions in the western Pacific resulted in safety measures being ignored or followed only half heartedly. In West Loch several LSTs (Landing Ship Tank) were being loaded with ammo and other explosives.
The explosions destroyed several ships and killed I have no idea how many. In shots of the area posted to Google Earth you can see a couple of the LSTs still there, half or mostly sunk. Most of the wreckage was quietly salvaged from the bottom and dumped beyond the 100 fathom curve. Interestingly, mixed in with that wreckage is one of the midget submarines the Japanese used on December 7. The mess from the chain reaction explosions was so great no one recognized it for what it was. IIRC both torpedos appear to have been fired unlike the midget USS
Ward had sunk.
Needless to say, I recommend that if you ever get to Hawaii visit the USS
Arizona Memorial and Punchbowl and pay your respects to the men who fell on 12/7/41.
